Necklace cellphone

I think it's time for a smaller, less intrusive, less- "are you happy to see me? or is that your smartphone?" bulging devices.

The quick-and-dirty sketch below depicts a wearable cellphone that is worn as a necklace. It uses voice commands and a tiny-winy touchscreen.

When you want to use the earphones, you rappel the device upwards which tightens the grip on your neck and frees up some wire so that the earphones can reach your ears. The sound is fed to the earphones by two conductive connections located in an optimal length location along the wires which the device clicks in to when the wires slide thorough it.
